NUMBERlNG-VIACHINE.;

SPECIFICATION forming part of Letters Patent No. 320,103, dated June 16,1885.

Application filed April 23, 1884. (No model.) I

To all whom, it away concern:

Be it known that I, EDMOND A. \VARREN, of the city of Brooklyn, in the county of Kings, in the State of New York, have invented a new and useful Improvement in Numberingdvlachines, of which the following is a specification, reference being had to the accompanying drawings.

In the various uses to which what are known as numberirig-machines, for printing consecutive numbers, can be put, it is sometimes desired to print numbers in regular succession once each, sometimes to repeat the printing of each of successive numbers several times, and sometimes to print alternate numbers.

One object of this invention is to provide for making the necessary changes in a numbering-machine to adapt it to the above-mentioned variations in the order of the numbers easily and quickly, and without requiring the removal of any parts of the machine and the substitution of other parts for them.

To the above end one part of myinvention consists in a means of controlling the opera tion of the change-pawl, which acts on the ratchet-wheel of the mimbering-head forturning the nu mbering-wheels, whereby the action of the said pawl and the consequent turning of the numbering-wheels may be suspended during a greater or less number of impression movements of the numberinghead, according to the number of times that the printing of each number is desired. Another part of the invention consists in means of varying the operation of the aforesaid pawl in such manner that it may be made to turn the ratchetwheel of the numbering-head one or more teeth, according as it is desired to print the numbers in regular or in alternate order.

The invention also consists in novel means, hereinafter described, of operating and ad justing the operation of the inking apparatus in a numberingprcss.

The invention further consistsin a new kind of gage-holder, which provides for the easy and expeditious adj ustment of the gage.

In the accompanying drawings, Figure 1 is a right-hand side view of the upper part of a numberirig-machine with my improvement. Fig. 2 is a front view of the same. Fig. 3 is and its stop-pawl. Fig. 4 is a front view of the dog for operating the repetitioirwheel, showing it in an inoperative position. Fig. 4" is a side view of the upper part of the change-pawl.

Fig. 12 is aside view of some of the details of the inking apparatus.

Similar letters of reference indicate corre sponding parts in the several figures.

A is the framing of the machine, provided with the usual guides, a a, for the upright slide B, to the lower end of which the numberinghead 0 is attached, and which is or maybe operated in the usual manner through a lever, D, and rod E from a treadle. The numberjug-head and its number-wheels I) b may be of the usual or any suitable kind and provided with the usualratchet-wheel, 0, through which the unit\vheel I) derives motion on its axis whenever desired, while the nuin'beringhead makes an upward movement from the changepawl d, pivoted to the framing at d. The numbering-head also contains the bearings for and carries the main shaft F of the inking ap paratus, which, as is common, is furnished at each end with a toothed sector, F, gearing with one of the fixed racks F secured to the framing, for the purpose of imparting to the said shaft the necessary oscillating motion as the numbering-head moves up and down.

G is what I call the "repetition-wheel" having ratchet-teeth on its periphery, and having in its face holes 0 e, corres i onding with said teeth, and numbered, consecutively, l 2 3 4, &c. This wheel is pivoted by a pin, f, to the lower guide, a, or other convenient part of the front of the framing, and it has attached to it at its back a cam, G, consisting of aplain circular and concentric ring having a notch, f. (Shown plainly in Fig. 3 and dotted in Fig. 4.) The rear edge or cam-surface of this ring eonstitutes a bearing for a pin, (P, which is secured in a prolongation of the change-pawl d, above its pivot d, and it is only when the said pin (Z is in or opposite the notch f ofthe cam that the change pawl d is capable of operating on the ratchet-wheel c, the said ring holding it out of gear at all other times. The said wheel G also has applied to its back a coiled spring, which always exerts a tendcncy to turn it in the direction of the arrow. (Shown in Fig. 4.) When the notch f of the cam is opposite the pin (2", the pawl-spring (1. applied to the change-pawl (1, holds the said pin in the said notch, the square upper side of which bears against the said pin in such manner that the latter serves as a stop by which the cam and the wheel G are prevented from being turned by the spring 5/, which then simply holds the wheel stationary. YVhen the wheel is so held stationary, the machine may be operated to print either consecutive or alternate numbers only once each, the pawl (Z being allowed to turn the ratchet-wheel 0 one tooth during every upstroke of the numbering-head, the slight movement required for the pawl to slip over the teeth in the downward stroke of the head being permitted by the depth of the notch f.

The repetition of the printing of a number is caused by suspending the operation of the change-pawl (Z, and this suspension is what the cam G, attached to the repetitiouwheel, is intended to do, and in order to do it the said wheel is turned one tooth during each of as many strokes of the numbering head as there are repetitions to be made, the first downstroke ofthe head turning the wheel far enough for the pin (2 to be moved out of the notch f by the action of the inclined side of the said notch, and successive strokes of the head causing the turning of the wheel, so that the face of the cam-ring continues to hold the pawl out of gear until it is desired to stop the repetition and print another numbcr,when the repetition-wheel is allowed to be turned back by the spring g to the position for the pin (1 to fall into the notch f, and permit the pawl d to come into gear and turn the ratchet c during the next stroke of the numbering-head.

I will now describe the means of turning the repetition-wheel to repeat the priuting,and of regulating or determining the numberof times it is turned, and the number of repetitions of the number produced.

The turning of the repetition-wheel for this purpose is in the opposite direction to that produced by the spring g,and indicated by the arrow in Fig. 4, and is produced by the operation on the ratchet-teeth of said wheel of a dog, 7r, carried by the arm 6* of a short rockshaft, 75', which works in a fixed bearing in a small bracket, secured on the lower guide. This rock-shaft has an arm, 7;, which is con- :nected by a rod, with an arm, 7;, firmly attached to the slide B. The turning takes place during each downward movement of the slide, and during the upward movement the repetition-dog 7c slips over the ratchet-teeth, being permitted to do so by its pivoted connection 75 with the arm 75* and the spring 75 the lattcr holding the pawl against a stop-pin, It, on the arm 70*, as shown in Fig. 2 in bold outline, which keeps the pawl rigid to the arm when moving in a direction to turn the wheel, but allows it to yield in going back. This connection of the dog also allowsit to be turned back to and held by the spring k" in theinoperative position illustrated in Fig. 4 when it is not desired to repeat the numbering, but is desired to leave the pawl (Z to operate at every stroke. The turning back of the repetitionwheel after every opera-tion produced by the dog 70 is prevented by a stop-pawl, H, (shown best in Fig. 4,) which is pivoted to the frame by a fixed pivot, h, in a position to engage with the ratchetteeth of the said wheel, as shown in bold outline in Fig. 4. This stoppawl has on its head a notched projection, 7r, whose notch engages the end of a spring, hf, which is secured to the framing, and which will hold the said pawl either in gear with the ratchet-teeth, as shown in bold outline in Fig. 4, or out of gear therefrom. Secured to the front of this pawl is a tongue, h, which overlies the face of the repetition wheel some distance, as shown in Figs. 1, 2, and 5.

The determination of the number of repetitions of the numbering is effected by means of two pins, 2' and j, inserted in the l'oles c c in the repetition-wheel G. The pin '11, which I call the zeropin, is permanently fixed in the wheel in such a position that when the notchf of the cam G is opposite the pin (Z of the change-pawl (Z the said pin t presses against the tongue hin adirection to hold the stop-pawl H in gear with the ratchet-teeth. The other pin, j, which I. call the variation pin, is set in either of the holes 2 3 1, according to the number of impressions of each number required. Thus it' two impressions are requireththe said pin is placed in the hole 2, and if three are required it is placed in the hole 3, and so on.

The operation of repeating is as follows: The variation-pin j having been set in the proper hole c of the repetition-wheel, the machine starts with the zero-pi 11 against the tongue h, as just above described. Thefirstdownstroke ol" the numberinghead causes the dog is to turn the repetition-wheel one tooth,and so turn the cam G far enough to throw the pin (Z of the change-pawl out of the notch f, and so render the said pawl inoperative. At every downstroke of the numberinghead this operation of the dog on the repctitioirwhcel is repeated, the said wheel being prevented by its stoppawl H from returning until the variationpin j strikes the tongue 71.,which may be called the unlocking-piece, and throws the stop pawl H out of geaigand so allows the spring g to turn back the wheel and bring the camnotchf opposite to the pin d of the change pawl (Z and allow the said pawl to assume an operative condition, so that in the next up stroke of the nuinberinghead it will turn the IIO ratchet of the nu mbering-head and change the number. The operator of the machine (who cannot fail to have noticed the flying back of the repetition-wheel) now, before making another downstroke, takes hold of one of the pins t j and turns back the said wheel until the zeropin 13, coming under the tongue It, brings the pawl into gear again, and the next downstroke, before producing the impression, causes the dog to turn the repetitionwheel and its cam far enough to throw the pin d out of the cam-notchf, and throw the change-pawl out of gear, where it remains during successive strokes of the machine until the pin j again strikes the unlocking-pieceh, and knocks the pawl H out of gear and permits the return of the wheel and cam to the position to permit again the operation of the change-pawl.

The repetition-wheel may have a large nu mber of holes and teeth, and so provide for numerous repetitions of consecutive or alternate numbers. If a greater number of repetitions is required than is provided for by the said wheel, the dog is may be turned out of gear, as shown in Fig. 4, and the wheel locked by the pawl in a position to hold the change-pawl (1 out of gear.

In order to provide for turning the changewheel 0 either one tooth at a time to print consecutive numbers or two tetehat a time to print alternate numbers, as is often required, the pin (1 in the upper part of the changepawl (I, is made adjustable forward and back ward in a slot, cit-(shown in Fig. 4 provided for it in the pawl, and capable of being secured in either the forward position shown in Figs. 1 and 4 or in the backward position shown in Fig. 1 by a thumb-nut, (P, applied to a screw-thread on the said pin, the said screw thread and nut serving to clamp the collar cl, Fig. t, on the said pin against the inner face of the upper part of the pawl. \Vhen the said pin is inthe forward position, (shown in Figs.1 and 4B,) its bearing against the cam G will only permit the point of the pawl to approach near enough to the vertical plane passing through the axis of the change-wheel c as to enable it to turn the said wheel one tooth at a time; but when the said pin is in the backward position (shown in Fig. 4") the point of the pawl may approach nearer to said line, and so be permitted to engage with the ratchetwheel earlier in the stroke and remain in engagement with one tooth long enough to turn it a distance equivalent to two teeth. This adjustment of the pawl may be used either in repeating or for printing the numbers coir secutively or alternately without repeating.

I is theinking-table,plaeed behind the numbering-head, with its face presented in a forward direction and inclined, as shown in Fi 1. It is arranged on a shaft or axle supported in a stationary arm, A, secured to the fran1- ing A, and it has no other than a simple rotary motion, its axis being fixed. Its rotary motion is produced by the action upon a ratchet-wheel, I firmly secured to it, of a pawl, I, which may derive motion by a connection with the lever D or from some other suitable moving part of the machine.

J is the inking-roller, the shaft J of which is carried in the lower ends of two levers, K K, which work on fulcrum-pins Z1, secured in the two arms F F, fast to the rock-shaft F. The upper ends of the said levers K K are connected by springs m with the upper parts of the said arms F F. The movement of the roller over the table is produced by the oscillation of the rock-shaft F, which-is produced.

by the sectors F, hereinbefore described, running in the fixed racks F as the numberinghead moves up and down, and the levers K K, in which the roller is carried, being allowed an independent movement, the roller is permitted to be brought by the springs m with a nearly equal pressure over all parts of the surface of the table without requiring the table to have any oscillating movement. The table having only a rotary motion and being. held firmly at a fixed inclination, the inkingroller can pass all the way from top to bottom of its face, and therefore the whole of the surface of the table can be utilized. Moreover, the ink-surface of the table being in front, its condition may at all times be seen by the operator.

For the purpose of adjusting the inkingroller to the printing surfaces of the number ingwheels, set-screws n a (shown best in Fig. 1.2) are screwed through lugs 12 n,providcd on the arms F F,and made to press upon the levers K K in a manner to bring the roller nearer to or farther from the shaft F, which is directly over the axis of the numberingwhecls, and thereby to make the roller come more or less close to or press harder or not so hard on the printingsurfaces.

P is the bar, at the extremity of which is formed the gage-holder, the said bar being adjustably attached in the usual or any suitable manner to the frame of the machine. In Figs. 2, 5, 6, 7, S, 5), 10 the front end of this bar is formed into a clamp to receive the piece of card or stiff paper 1), commonly used as the gage, the fixed jawp of the clamp being formed by reducing the upper side of the bar 1 to a flat surface, and movable jaw 1) being com posed of a thin and flexible steel blade attached to the bar I at the end farthest from the end of the said bar by aserew or rivet, p. The end of the bar P, which is left round, is fitted with a thimble or collar, Q, which turns freely upon it, and this thimble has in it a notch, q, of a size and form to allow the end of the blade 1) to pass in and out, as will be understood by reference to Fig. 6. Near the head or outer end of this collar or thimble there is a slot, q, to receive a pin, (j, which is screwed into the bar P, and which keeps the thiinble from slipping off, but permits it to turn sufficiently to insert the piece of card or paperintotheclamp. Thethimbleisturnedto the position shown in Figs. 6, 7, and 9, in which IIO the end of the blade or movable jaw p is free to enter the notch q and spring slightly outward. On the paper or card having been inserted the thimble is turned, and the notch, passing the blade, the closed portion of the thimble covers and presses on the end of the blade or movable jaw, as shown in Fig. 8, and produces the clamping of the paper, which is permitted to be removed or readjusted by simply turning back the thimble to the position first mentioned.

The clamp form of the gage-holder affords very much greater convenience for the attachment, adjustment, and changing of the gage than is afforded by the common method of fastening a piece of cloth to the holder and pasting the card or paper gage to this cloth.

In the modification shown in Fig. 11 there is attached to the bar P a clamp composed of a fixed jaw, R, and a movable jaw, S, hinged thereto at I, and a clamping-screw is applied at a.

hat I claim as my invention, and desire to secure by Letters Patent, is.
